Keith wrote the expression 10d to represent the number of dimes in d dollars. Is Keith's expression correct? Explain.
Answered by Ms. Sue
Right.

Answered by Cody
Can you explain? I was thinking that d/10 would be the answer, since there are 10 dimes in a dollar. If the expression was 10d wouldn't that mean 10 dimes X 1 dollar?
Answered by Ms. Sue
10 dimes = $1.00
20 dimes = $2.00
30 dimes = $3.00

So --
10 times 3 = 30
10 times 4 = 40
